چکیده
The title compound, C(7)H(7)NO(3)·H(2)O, which crystallized as a hydrate, was obtained from an extraction of the plant species Saussurea atkinsonii of the asteraceae family collected from the hilly area (Ayubia) of Pakistan during the flowering season. The dihedral angle between the benzene ring and the carboxyl-ate group is 25.64 (5)°. In the crystal, the packing is consolidated by N-H⋯O and O-H⋯O hydrogen bonds, as well as weak aromatic π-π stacking [centroid-centroid separation = 3.9365 (9) Å] and C=O⋯π inter-actions.

The title compound, C(9)H(11)N(2)O(5) (+)·Cl(-)·H(2)O, was synthesized from (1S,2S)-2-amino-1-(4-nitro-phen-yl)propane-1,3-diol in four steps. As demonstrated by this work, no racemization occurs during this synthetic procedure. The crystal structure displays many inter-molecular hydrogen bonds between the acidic cation, chloride anions and the water mol-ecules, forming a three-dimensional netw...
